Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical equipment technology, specifically to an auxiliary guiding structure for syringe gripping. Background Technology

[0002] After the syringe is pipetted from the aspiration chamber of the drug preparation equipment, it needs to be rotated 180° to reach the other side of the equipment. After rotation, the next step is for the robotic arm to pick up the syringe. However, if there is no guide, the robotic arm's gripping position may be deviated, resulting in operational errors. Therefore, it is urgent to develop an auxiliary guide structure for syringe gripping to solve the problems in the existing technology. Utility Model Content

[0003] The purpose of this invention is to provide an auxiliary guiding structure for syringe gripping, which allows the syringe to be restrained by the guiding groove and spring plate during the rotation of the rotating disk, so that the syringe is always kept in the matching groove of the rotating disk and the relative position does not change, thereby ensuring the gripping accuracy of the robot in subsequent steps. Moreover, the structure is simple and easy to use, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] The auxiliary guiding structure for syringe gripping includes a frame and a syringe, and also includes:

[0006] A drive mechanism is disposed on the bottom inner wall of the frame;

[0007] A rotating mechanism is mounted on the output shaft of the driving mechanism. The rotating mechanism includes two partitions and a rotating disk disposed on the outer walls of the two partitions. The top outer wall of the rotating disk is provided with an adapter groove, and the syringe is suspended in the adapter groove. Guide blocks are provided on both outer walls of the partitions, and a guide groove is provided on one outer wall of the guide block. The outer wall of the syringe abuts against the inner wall of the guide groove.

[0008] The inner wall of the frame is provided with a bottom mounting plate, the top outer wall of the bottom mounting plate is provided with equally spaced support columns, the outer wall of the support columns is provided with guide blocks, the inner wall of the guide blocks is provided with spring sheets, and the outer wall of the spring sheets abuts against the outer wall of the syringe.

[0009] By adopting the above technical solution, when the drive mechanism drives the rotating disk to rotate, the syringe is blocked vertically by the adapter groove to prevent it from falling. The centrifugal force generated by the rotating disk during rotation will cause the syringe to slightly deviate away from the center. At this time, the spring plate of the guide block contacts the outer wall of the syringe, giving the outer wall of the syringe a slight elastic force, which can prevent the syringe from continuing to deviate outward. This process continues until the syringe is completely rotated to the other side of the frame, which improves the accuracy of the robot arm in grasping the syringe in the next step. The structure is simple and reasonable.

[0010] As a further embodiment of this utility model: the driving mechanism further includes a driving cylinder disposed on the inner wall of the bottom of the frame, the output shaft of the driving cylinder is connected to a rotating shaft through a coupling, and the two partitions are distributed at equal angles on the outer circumference of the rotating shaft.

[0011] As a further embodiment of this utility model: both outer walls of the partition are provided with blocking blocks, and the outer walls of the blocking blocks are provided with grooves, the grooves being consistent with the projected shape of the adapter groove in the vertical direction.

[0012] By adopting the above technical solution, the angle between the two partitions is 180°, and a rotating disk for placing syringes is set on each side of the partition. Therefore, this structure can ensure continuous delivery of syringes with high efficiency.

[0013] As a further embodiment of this utility model: the top outer wall of the bottom mounting plate is provided with evenly distributed mounting holes, and the coupling is disposed on the inner wall of the mounting holes.

[0014] As a further embodiment of this utility model: the rotating mechanism further includes a bearing disposed at the top end of the rotating shaft, and the bearing is disposed on the top inner wall of the frame.

[0015] As a further embodiment of this utility model: the opening shape of the guide block is semi-circular, the two ends of the spring sheet are disposed at the two ends of the opening of the guide block, and the shape of the spring sheet is consistent with the shape of the opening.

[0016] As a further embodiment of this utility model: the spring sheet is made of alloy spring steel, and the surface of the spring sheet is a polished smooth structure.

[0017] By adopting the above technical solution, the spring sheet is set to a smooth surface structure, and the outer wall of the syringe is also a smooth structure. Therefore, the friction generated when the syringe comes into contact with the surface of the spring sheet is small. Thus, the spring sheet can minimize its influence on the syringe while maintaining its position, and the position of the syringe will not change due to excessive friction.

[0018] As a further embodiment of this utility model: the projection shape of the guide block in the vertical direction is fan-shaped, and the angle of the fan shape is less than 180°.

[0019] In summary, this application includes at least one of the following beneficial technical effects:

[0020] 1. Excellent guiding effect: No positional deviation occurs during syringe transfer. Through the cooperation of the guiding groove on the guiding block and the spring plate in the guide block, the position of the syringe can be kept unchanged during the movement of the syringe around the rotating axis, thereby improving the accuracy of the robot arm in grasping the syringe in the next step.

[0021] 2. The influence on the syringe during the alignment process is minimal. When the rotating disk does not rotate or rotates 180°, neither end of the guide block reaches the edge of the opening of the adapter groove on the rotating disk. This setting is to prevent the guide block from obstructing the syringe when the robot arm grasps it. The spring sheet is set to a polished smooth structure, which can further reduce the influence on the syringe during the alignment process and improve the grasping accuracy.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Reference Figure 1 , Figure 3 , Figure 4 and Figure 5 In this embodiment, the auxiliary guiding structure for syringe gripping includes a frame 12 and a syringe 4, and further includes:

[0031] The drive mechanism is located on the bottom inner wall of the frame 12;

[0032] The rotating mechanism is mounted on the output shaft of the drive mechanism. The rotating mechanism includes two partitions 3 and a rotating disk 5 disposed on the outer walls of both sides of the partitions 3. The top outer wall of the rotating disk 5 is provided with an adapter groove, and the syringe 4 is suspended in the adapter groove. Guide blocks 9 are provided on both outer walls of the partitions 3. A guide groove 8 is provided on one outer wall of the guide block 9. The outer wall of the syringe 4 abuts against the inner wall of the guide groove 8.

[0033] The inner wall of the frame 12 is provided with a bottom mounting plate 13, the top outer wall of the bottom mounting plate 13 is provided with equally spaced support columns 14, the outer wall of the support columns 14 is provided with a guide block 6, the inner wall of the guide block 6 is provided with a spring sheet 11, and the outer wall of the spring sheet 11 abuts against the outer wall of the syringe 4.

[0034] In use, after the syringe 4 is suspended on the rotating disk 5, the top of the syringe 4 is positioned precisely in the guide groove 8 of the guide block 9. Activating the drive mechanism rotates the partition 3 and the rotating disk 5, allowing the syringe 4 to be transferred from one side of the frame 12 to the other. During this process, the adapter groove on the rotating disk 5 prevents the syringe 4 from falling due to gravity. However, due to centrifugal force generated during rotation, the syringe 4 may shift outwards along the center of the adapter groove. However, since the guide block 6 is fixed to the support... The spring plate 11 inside the guide block 6, located on the support column 14, pushes the syringe 4 into the guide block 6 when the rotating disk 5 drives it. This spring plate 11 inside the guide block 6 abuts against the outer wall of the syringe 4, thus providing a pushing force towards the center of the syringe 4. This keeps the syringe 4 in the guide groove 8 of the guide block 9, preventing it from shifting outward or to the side. The spring plate 11 in the guide block 6, the guide block 9, and the guide groove 8 work together to prevent the syringe 4 from shifting, thereby preventing the robotic arm from shifting when it grabs the syringe 4 in the next step and increasing the accuracy of the syringe 4's position.

[0035] The bottom mounting plate 13 has evenly distributed mounting holes on its top outer wall, and the coupling 2 is located on the inner wall of the mounting holes.

[0036] Specifically, the rotating mechanism also includes a bearing located at the top of the rotating shaft 7, which is located on the top inner wall of the frame 12.

[0037] Reference Figure 2 and Figure 3 In this embodiment, the driving mechanism also includes a driving cylinder 1 disposed on the inner wall of the bottom of the frame 12. The output shaft of the driving cylinder 1 is connected to a rotating shaft 7 through a coupling 2. Two partitions 3 are distributed at equal angles on the outer circumference of the rotating shaft 7. Both sides of the outer wall of the partition 3 are provided with blocking blocks 10. The outer wall of the blocking block 10 is provided with a groove, and the groove is consistent with the projection shape of the adapter groove in the vertical direction.

[0038] The start-up drive cylinder 1 drives the rotating shaft 7 to rotate via the coupling 2. The rotation of the rotating shaft 7 drives the partition 3, the rotating disk 5, the blocking block 10, and the syringe 4 on the rotating disk 5 to rotate. After the rotating disk 5 rotates 180°, the relative positions of the rotating disk 5, the guide block 9, and the blocking block 10 will not change. At the same time, the position of the guide block 6 is fixed. Therefore, when the syringe 4 rotates to the other side, the guide block 6 will not block the gripping of the syringe 4. The structure is reasonable.

[0039] Reference Figure 3 and Figure 4 In this embodiment, the opening shape of the guide block 6 is semi-circular, and the two ends of the spring sheet 11 are located at the two ends of the opening of the guide block 6. The shape of the spring sheet 11 is consistent with the shape of the opening. The spring sheet 11 is made of alloy spring steel, and the surface of the spring sheet 11 is a polished smooth structure.

[0040] During the rotation of the syringe 4, the spring plate 11 in the guide block 6 acts as a guardrail for the syringe 4, protecting it. At the same time, the outer wall of the spring plate 11 is smooth with minimal friction, so it will not affect the position of the spring plate 11 on the rotating disk 5. Even under the action of thrust, there is a certain friction between the spring plate 11 and the syringe 4, but the spring plate 11 will only cause the syringe 4 to rotate in the adapter slot of the rotating disk 5, without affecting the overall position of the syringe 4.

[0041] Reference Figure 2 and Figure 3 In this embodiment, the projection shape of the guide block 6 in the vertical direction is a fan shape, and the angle of the fan shape is less than 180°.

[0042] In order not to obstruct the next step of the robotic arm's grasping of the syringe 4, the opening angle of the guide block 6 is approximately between 150° and 170°, and the opening angle of the guide block 6 is evenly distributed around the partition 3. That is, when the rotating disk 5 is not rotating, the shape of the guide block 6 on both sides of the partition 3 is completely symmetrical. That is, when the entire rotating disk 5 rotates 180° or is in the original position, neither end of the guide block 6 will exceed the opening of the adapter groove on the rotating disk 5. In this way, the guide block 6 can be prevented from blocking the insertion and removal of the syringe 4.

[0043] Working principle:

[0044] The start-up drive cylinder 1 drives the rotating shaft 7 to rotate via the coupling 2. Simultaneously, the rotating shaft 7 rotates the partition 3, the rotating disk 5, the blocking block 10, and the syringe 4 on the rotating disk 5. Once the syringe 4 is suspended on the rotating disk 5, its top is positioned within the guide groove 8 of the guide block 9. The start-up drive mechanism then rotates the partition 3 and the rotating disk 5, allowing the syringe 4 to be transferred from one side of the frame 12 to the other. During this process, the adapter groove on the rotating disk 5 prevents the syringe 4 from falling, thus preventing it from falling. It will not fall due to gravity, but due to the centrifugal force generated during rotation, the syringe 4 may shift outward along the center of the fitting groove. However, since the guide block 6 is fixed on the support column 14, when the rotating disk 5 drives the syringe 4 into the guide block 6, the spring plate 11 inside the guide block 6 abuts against the outer wall of the syringe 4, thereby giving the syringe 4 a pushing force towards the center, keeping the top of the syringe 4 always in the guide groove 8 of the guide block 9, thus preventing the syringe 4 from shifting outward or to the side.
